t^{2}+3t+2=0
Whakakapia te t mō te x^{2}.
t=\frac{-3±\sqrt{3^{2}-4\times 1\times 2}}{2}
Ka taea ngā whārite katoa o te momo ax^{2}+bx+c=0 te whakaoti mā te ture pūrua: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. Whakakapia te 1 mō te a, te 3 mō te b, me te 2 mō te c i te ture pūrua.
t=\frac{-3±1}{2}
Mahia ngā tātaitai.
t=-1 t=-2
Whakaotia te whārite t=\frac{-3±1}{2} ina he tōrunga te ±, ina he tōraro te ±.
x\in \emptyset
I te mea ko x=t^{2}, ka riro ngā otinga mā te arotake i te x=±\sqrt{t} mō t tōrunga.
